Abstract
In a process of producing anhydrous magnesium chloride of the type comprising: A. Mixing together a magnesium chloride hydrate, said hydrate containing minor amounts of water-soluble sulfate and boron compounds as impurities with diethyl ether of tetraethylene glycol to prepare 0.1-6.0% by weight slurry of MgCl2 in the diethyl ether of tetraethylene glycol and an azeotropic agent having a boiling point less than the diethyl ether of tetraethylene glycol in a quantity sufficient to remove water from said slurry the improvement which comprises substituting dibutyl ether of tetraethylene glycol for the diethyl ether of tetraethylene glycol.
